1 Be it known'that I, WILSON E. PORTER, a citizen of the United States, residing at New aven, in the "county of New Haven and 52ntiit of Connecticuflhave invented a new and useful Improvement in F ront-Winding -Clock-Movements; and I do hereby declare Q- the following, when, taken inn connect-ion "with the accompanying drawings and the characters of reference marked thereon, to be 31* full, clear, andexact description of the saute, and which said drawings constitute part of this applicationfand represent, in

' Figure l 'a-view front elevation of a 3.5

front-w'mding eightday-marine cl o ck-moven 'ent constructed in accordance with my .invention. Fig; 2 a corresponding view with q the front movement plate and the front Y interm'ediate plate removed. Fig. 3 a view ofthe movement in horizontal section on the line a pb of Fig. 1. My invention relates front-winding eight day marine clocksuch use, the object being" to produce anmovements primarily designed to be used in apton obile aclocks, though not limited to eight-dayv movement ofisniall diameter in which the winding-arbor is positioned in the dial so as not to mutilate, or. at least not '39 to"seriously mutilate thefigures thereof.

A'fiirther objectof'iny invention is to produce-"a clock-movement in which the wheels of the winding-train are held in place 2 without securing them permanently to their 36.

mediat e movement-plates placed so close to-.

gether as to leave but a narrow space be-' arbors, by interposing them bet-ween intertweenthem. v v

- \Vith these ends 1n View my invention consists in a front-winding eight-day 'inarine clock-movement haying certain details of construct-ion and" combinations of parts as will be hereinafter-described and pointed out in the "claims In carrying out my invention as herein ,shown, I employ a circular front movementplate 2, a corresponding rear movementplate 3,-land circular frontand rear interinediate movement-plates 4 and 5, these four plates being secured together bypillars 6 passing through spacing sleeves 7, 8 and 9 respectively varied in length in. accordance with the spaces required between the said plates, the rear ends of the said pillars. being to an improvement threaded and furnishedwith nuts 10 which,

however,may bereplaced by screws entering threaded counterbores in the pillars. An

eight-day main-spring, not shown, is located --1I 1 a main-spring barrel 11 placed between the rear plate 3 and the rear intermediate movement-plate 5, and mounted upon a j 'm'ain-spring arbor l2 journaled in the centers of the said plates and therefore concen-.

trio with the clock-movement. The forward end .ofthe said arbor-12 projects into the placeby its bearing against the adjacent faces of the said. plates at and 5' without being secured to the squared end 18 of the arbor.

in the platefi, the plate 4 being formed with head of the stud. l he pawl is maintained A pawl 15 co-acting with the wheel '14: is mounted upon a shouldered stud -16 riveted inengagement wit-l the teeth of the wheel .14 by means of 'a s ring l8 formed at its outer end with an integral finger 19 by means of which it is moiinted in the plate 5 as clearly shown inFig. 3. The ratchet 14; j is meshed into by a winding-wheel 20 corresponding to it in diameter and formed movement plate 2 and the front intermediate plate 4; theprojecting forwardend 24 of the arbor 22 being squared for the reception of the winding-key, which is not shown.

It will be seen from the foregoing that the ratchet wheel 14 and the winding wheel 20 are held in place-by the plates 4 and 5, the separation between which is just wide enough to permit the introduction of the wheels between them, whereby the fixed attachment; of the wheels to the main-spring arbor 12 and the winding-arbor 22 respectively is rendered unnecessary. It will also be observed that under my construction the winding-arbor 22 is brought to the front of .-theclockamoveinent through the front movemerit-plate 2 thereofin such a position that its-necessitates little or no mutilation of the figures onthe dia1,"whic'h .1s not shown. Of

with a square central opening adapting it to beset over the squared rear end 21of'a wind- 1e and 20 the Windingerbor 22 may he po-- course by changing the sizes of the WhQBiE;

sitiotned anywhere between the center enoi periphery of the front i'novenient-piate 2- anywhere where it will not co icie with other parts. This construction imposes, no iin'iitet-ions upon the sizeot the main-spring barrel 11 since the some ooateti entirely to the real of; the i'atchet and Wind Wi'ieeis ithout interfering With. other PillLS of the movement.

The squared forwardend 1.3 of the mainspring arbor 12 is fcrniech as shown. with e clearance recess for the reception of the rear pivot of the center-arbor "26 which is journeled at its rear end in the center of the front intermediate plate 4t, the forward end of the arbor26 being jc-urneieii in the center of the front,movement-plate 2. The said centeoarboi- 26 carries the usual center pinion. 2'? to which the center.whee1 28 is at teched, the said wheel and pinion being located just Within the front movement-plate 2. Upon the projecting forward end of the centererhor i'. mount the cannon pinion 29 with the socket Wheel 30 in front of it. The main-spring barrel 11 is provided, as usueh with e mein Wheel 31 which meshes into 22 pinion, not shown, but :"Torrninig; a pert the oft-dine y timetmin.

The time movement and tiiei-woi'h are not :fuily shown as they constitute no part of my present invention and may be any oroiinary construction.

mot rear me einent plates and front and rear intermediate movement plates, of e iminspifing sire located between the rear i 5e and the intermediate plate, ineinspringerhor for the :l barrel, a winding :2 her mounted at "its rear end in the saidv front ii'itermediete move Jhite and projecting forward through in u the front movement-plate and hehi in place thereby and Wheels interposed between the s ifi intermediate plates and connecting the said al'hci's.

In efront-Winciing ciocimnovement, the eomhinatio l with front :Uhii rear mevementplates, of i "til and your intei'ineciiete movement-plates, maii'i-spring he rrei ioceteci between the movement-plate end, the rear intermediate n'ioveinentplate a. main-spring arbor journeled in the rear n1ovement-piete and the lQ'dfi' intermeciietemovement-plate and i'ifiVifQf i forward end squared and projecting into the narrow space between the tWe intermediate movement-plates, e atchet-wheel loosely nioun'ied upon the said squared portion of the main-spring arbor, and interposi'ed between and held in piece by the said intermediate plates, at winding-erbor journaied in the f ont movement-plate and the front intermeoiate mewzmeutpiate :mciilaving its inner anti outer ends squared, and. e Winding-Wheel meshing into thesuid ratchet-Wheel, iocseiy mounted upon the squared inner end. the said winding-arbor and interposed between and hold in place by the said interl'nediate moi cut-plates.
